The nominal motor output (B11) can be used to determine an approximate
value for B48. The approximate value is calculated according to the following
formula: B48 = a * B11 + b
The coefficients a and b can be taken from the following table.
Inductance R
U-V
of the motor winding in mH. This value should only be
parameterized for third-party motors. The value can be autotuned with action
B41 autotuning.
Stator resistance R
U-V
of the motor winding in ohms. Processing with this
parameter is only possible for third-party motors. The value can be autotuned
with action B41 autotuning.
Leaked inductance as a part of overall inductance "Ls" of the motor.
The parameter indicates the degree to which the motor is magnetically
saturated at the nominal point. The parameter is important for the control
accuracy of control modes 2:ASM - vector control and 3:ASM - Sensorless
vector control in the field weakening range.

Information
The default value is adequate for most motors and applications.
Adjustments are only necessary in some circumstances when
connecting a third-party motor. In these cases the value can be
autotuned with action B41 autotuning. However, this adjustment
should not be performed until you have consulted with STOBER.
